Electrochemical silver particulate films

Negatively charged monolayers floating on an aqueous silver nitrate solution Ag Metallic silver particulate films generated electrochemically at monolayer surfaces could be transferred at any stage of their development to solid substrates 566, 567...

Importantly, no silver particulate film formation could be observed at the air/liquid interface, either in the chemical or in the electrochemical generation, in the absence of surfactants or under monolayers prepared from positively charged surfactants.
